For the redundant setup of 2 power supplies with 30A or 40A rated output current, two redundance modules will be necessary. In this case one redundance module is assigned to one power supply respectively and the terminals “In 24V-1” and “In 24-2” need to be interconnected on each module.

The picture and the description is about the connection of RM modules to final consumer, but my question is about the connection of 2 sitop power supply 40A and 2 redundancy module ( i mean the connection of V1 and V2 on two redundant modules.

But now that i'm thinking more, I thing this new attached picture must be correct

Caution: The redundance module is suitable for the redundant setup of two SITOP power supplies up to a rated output current of 20A each! For the redundant setup of 2 power supplies with 30A or 40A rated output current, two redundance modules will be necessary. In this case one redundance module is assigned to one power supply respectively and the terminals “In 24V-1” and “In 24-2” need to be interconnected on each module.

Then I think that each Redundancy Modul only have ONE SITOP power supply and the "In 24V-1" and the "In 24V-2" have to be interconnected to each other, so both modules have 30A or 40A and are connected to each other on the output + and -.

I hope that the answer will help, if you have still questions, don't hesitate to ask me.

All the best, LateNever say never, think in solutions, not in trouble......
